I'm also very worried if Ethereum continues to decline, I'm worried because many altcoins and ICOs are using the Ethereum platform, if Eth is increasingly destroyed the altcoin will also be affected and will be a big mess, I can't imagine all ICOs that have used the Ethereum platform should start their work again from the beginning.
I agree, but another thought is that it all looks like a piece of panic. All recover, and the altcoin will go up. But such a turn already as a warning signal can be considered and be more careful. The changes should be, and everything should be improved, as crypto is still developing.
